The European Green Belt initiative is a grassroots movement for nature conservation and sustainable development along the corridor of the former Iron Curtain. The term refers to an environmental initiative as well as the area it concerns. The initiative is carried out under the patronage of the International Union for Conservation of Nature and formerly Mikhail Gorbachev. It is the aim of the initiative to create the backbone of an ecological network that runs from the Barents to the Black and Adriatic Seas.

The European Green Belt as an area follows the route of the former Iron Curtain and connects national parks, nature parks, biosphere reserves and transboundary protected areas as well as non-protected valuable habitats along or across the (former) borders.

This is a list of primates described in the 2020s. As primates are a well-studied group, species that are unknown to science are rare. However, recent advances in DNA sequencing have allowed scientists to compare populations and test for distinct lineages in extant species. This list includes species that have been discovered, formally described, or brought to public light in the year 2020 or later. New primate species are recorded by the International Union for Conservation of Nature Species Survival Commission (IUCN/SSC) Primate Specialist Group, an organisation chaired by primatologist Russell Mittermeier and deputy chaired by Anthony Rylands. In the previous ten years 36 primates were described.

Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change, and the illegal wildlife trade. The IUCN estimates that 42,100 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (CBD). There are also numerous nongovernmental organizations (NGO's) dedicated to conservation such as the Nature Conservancy, World Wildlife Fund, and Conservation International.

Lurë-Dejë Mountain National Park (Albanian: Parku Kombëtar "Lurë-Mali i Dejës") is a national park in northeastern Albania, spanning an expanded area of 202.42 km (78.15 sq mi) since 2018 by encompassing the entire section of Kunora e Lurës, former Zall-Gjocaj National Park, and Dejë Mountain. The park was originally established in 1966 to protect the various ecosystems and biodiversity as Lura National Park. The altitude vary from 1,500–2,300 m (4,921–7,546 ft). The International Union for Conservation of Nature (IUCN) has listed the park as Category II. Nevertheless, it is described as an important Bird and Plant Area, because it supports significant bird and plant species.

Llogara National Park (Albanian: Parku Kombëtar i Llogarasë/Llogorasë) is a national park centered on the Ceraunian Mountains along the Albanian Riviera in southwestern Albania, spanning a surface area of 1,769 ha (17.69 km). The park's terrain includes large alpine meadows, vertical rock faces, precipices and dense forests. Most area of the park is covered by forests and was established in 1966 to protect several ecosystems and biodiversity of national importance. The International Union for Conservation of Nature (IUCN) has listed the park as Category II. The region has been recognised as an important Bird and Plant Area, supporting significant number of species.

The park features outstanding diversity with the landscape ranging from the alpine peaks of the Ceraunian Mountains covered with snow in winter to the sunny Albanian Ionian Sea Coast in summer. At 1,027 m (3,369 ft), the Llogara Pass provides a striking scenery, with tall mountains overlooking the Albanian Riviera and several islands in the sea. The region experiences a mediterranean climate. This means that the summers are hot and the winters generally dry to warm to cool. Despite the vicinity to the mediterranean climatic region, an alpine climate prevails at the Maja e Çikës. Geomorphologically, carbonate rocks occupy most of the area, while the mountains are composed of limestones and dolomites.

An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular region. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting or harvesting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.

Human activity is a significant factor in causing some species to become endangered.

Seriatopora hystrix is a species of colonial stony coral in the family Pocilloporidae. It forms a branching clump and is commonly known as thin birdsnest coral. It grows in shallow water on fore-reef slopes or in sheltered lagoons, the type locality being the Fiji Islands. It is native to East Africa, the Red Sea and the western Indo-Pacific region. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being a "Vulnerable species".

The common stingray (Dasyatis pastinaca) is a species of stingray in the family Dasyatidae, found in the northeastern Atlantic Ocean and the Mediterranean and Black Seas. It typically inhabits sandy or muddy habitats in coastal waters shallower than 60 m (200 ft), often burying itself in sediment. Usually measuring 45 cm (18 in) across, the common stingray has a diamond-shaped pectoral fin disc slightly wider than long, and a whip-like tail with upper and lower fin folds. It can be identified by its plain coloration and mostly smooth skin, except for a row of tubercles along the midline of the back in the largest individuals.

The predominant prey of the common stingray are bottom-dwelling crustaceans, though it also takes molluscs, polychaete worms, and small bony fishes. It is aplacental viviparous: the embryos are nourished by yolk and later histotroph ("uterine milk") produced by the mother. Females bear 4–9 young twice per year in shallow water, after a gestation period of four months. The common stingray can inflict a painful, though rarely life-threatening, wound with its venomous tail spine. During classical antiquity, its sting was ascribed many mythical properties. This species is not sought after by commercial fisheries, but is taken in large numbers as bycatch and utilized for food, fishmeal, and liver oil. Its population is apparently dwindling across its range, and the International Union for Conservation of Nature (IUCN) assesses it as Vulnerable.

The Bramble Cay melomys, or Bramble Cay mosaic-tailed rat (Melomys rubicola), is a recently extinct species of rodent in the family Muridae and subfamily Murinae. It was an endemic species of the isolated Bramble Cay, a low-lying vegetated coral cay with a habitable area of approximately 5 acres (2.0 ha) located at the northern tip of the Great Barrier Reef in Australia. Described by researchers as having last been seen in 2009 and declared extinct by the Queensland Government and University of Queensland researchers in 2016, it was formally declared extinct by the International Union for Conservation of Nature (IUCN) in May 2015 and the Australian government in February 2019. Having been the only mammal endemic to the reef, its extinction was described as the first extinction of a mammal species due to anthropogenic climate change.

Episkopi Bay (Greek: Κόλπος Επισκοπής; Turkish: Piskobu Körfezi) is a bay west of the Akrotiri Peninsula on the south-western shore of Cyprus, between Paphos and Akrotiri. On the other side of the Akrotiri Peninsula is Akrotiri Bay. It is famous for its beaches and fish restaurants. Despite the Turkish invasion and ensuing ethnic division of Cyprus in 1974, a number of Turkish Cypriots chose to remain in the area.

Episkopi Bay is a nesting ground for green and loggerhead turtles, both of which are on the IUCN list of endangered species. Episkopi Turtle Watch is a local volunteer group dedicated to the conservation of the turtles and their nesting beaches.

A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.

Not all EW species are rare. An example is the Brugmansia genus, where all seven species are widely cultivated, but none are found in the wild.

The coyote (Canis latrans) is a species of canine also known as the American jackal, prairie wolf, and brush wolf. It is native to North America, and it is smaller than its close relative, the gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia; however, the coyote is generally larger.

The coyote is listed as least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans; urban coyotes are common in many cities. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013.

Suina (also known as Suiformes) is a suborder of omnivorous, non-ruminant artiodactyl mammals that includes the domestic pig and peccaries. A member of this clade is known as a suine. Suina includes the family Suidae, termed suids, known in English as pigs or swine, as well as the family Tayassuidae, termed tayassuids or peccaries. Suines are largely native to Africa, South America, and Southeast Asia, with the exception of the wild boar, which is additionally native to Europe and Asia and introduced to North America and Australasia, including widespread use in farming of the domestic pig subspecies. Suines range in size from the 55 cm (22 in) long pygmy hog to the 210 cm (83 in) long giant forest hog, and are primarily found in forest, shrubland, and grassland biomes, though some can be found in deserts, wetlands, or coastal regions. Most species do not have population estimates, though approximately two billion domestic pigs are used in farming, while several species are considered endangered or critically endangered with populations as low as 100. One species, Heude's pig, is considered by the International Union for Conservation of Nature to have gone extinct in the 20th century.

Funga is all the fungi of a particular region, habitat, or geological period. In life sciences, "funga" is a recent term (2000s) for the kingdom Fungi similar to the longstanding fauna for animals and flora for plants. The term seeks to simplify projects oriented toward implementation of educational and conservation goals. It highlights parallel terminology referring to treatments of these macroorganisms in particular geographical areas. An official proposal for the term occurred in 2018, despite previous use.

The Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN) in August 2021 called for the recognition of fungi as one of three kingdoms of life, and critical to protecting and restoring Earth. Funga was recommended by the IUCN in 2021. They ask that the phrase animals and plants be replaced by animals, fungi, and plants, and fauna and flora by fauna, flora, and funga.

The Gibraltar Nature Reserve (formerly the Upper Rock Nature Reserve) is a protected nature reserve in the British Overseas Territory of Gibraltar that covers over 40% of the territory's land area. It was established as the Upper Rock Nature Reserve in 1993 under the International Union for Conservation of Nature's category Ia (strict nature reserve) and was last extended in 2013. It is known for its semi-wild population of Barbary macaques, and is an important resting point for migrating birds.

Sage-grouse are grouse belonging to the bird genus Centrocercus. The genus includes two species: the Gunnison grouse (Centrocercus minimus) and the greater sage-grouse (Centrocercus urophasianus). These birds are distributed throughout large portions of the north-central and Western United States, as well as the Canadian provinces of Alberta and Saskatchewan. The International Union for Conservation of Nature classified theC. minimus species as endangered in 2020 and C. urophasianus as near threatened in 2016.

An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.

The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category.

Ponginae /pɒnˈdʒaɪniː/, also known as the Asian hominids, is a subfamily in the family Hominidae. Once a diverse lineage of Eurasian apes, the subfamily has only one extant genus, Pongo (orangutans), which contains three extant species; the Sumatran orangutan (Pongo abelii), the Tapanuli orangutan (Pongo tapanuliensis) and the Bornean orangutan (Pongo pygmaeus). All three species are listed as critically endangered by the International Union for Conservation of Nature (IUCN).

As of January 2020, the International Union for Conservation of Nature (IUCN) listed 203 critically endangered mammalian species, including 31 which are tagged as possibly extinct. Of all evaluated mammalian species, 3.5% are listed as critically endangered. The IUCN also lists 60 mammalian subspecies as critically endangered.

Of the subpopulations of mammals evaluated by the IUCN, 18 species subpopulations have been assessed as critically endangered.
